- Optimized correction for drone based optical and thermal data acquisitions
- Surface temperature retrieval for single band TIR
- Fully automatic processing and product generation
- Topographic illumination correction based on digital surface model input.
- Standard BREFCOR-based BRDF correction.
- Batch processing support
Reflectance Retrieval Features
- Physical reflectance retrieval method, including adjacency correction
